REFRIGERATOR CONSTRUCTION.

Specification 6f Letters Patent.

T 0 all "whom it may concern:

Be it known that we, LOUIS F. PERKETT and ED\VARD C. MADARY, citizens of the United States, residing at Traverse City, in the county of Grand Traverse and State of Michigan. have invented certain new and useful Improvements in Refrigerator Construction, of which the following is a specification.

This invention relates to improvements in refrigerator construction and one of the objects of the same is to provide an improved device of this character which will be constructed of fiber board, whereby the weight of the structure will be materially reduced and at the sametime will result in a moisture and heat proof structure and the cost of manufacture will be materially reduced.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction. combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawing illustrating the invention, and in which,

Figure l is a perspective view of an improved refrigerator of this character. constructed in accordance with the principles of this invention.

Fig. 2 is a transverse horizontal sectional view of Fig. 1.

Referring more particularly to the drawing, the numeral 10 designates corner uprights which may be constructed of any suitable material such as wood, and secured to these uprights to form the back and side walls 11, 12 are sheets of wood or paper fiber board, commonly known as straw board and are fastened to the uprights in any suitable manner, the edges of adjacent boards being secured together in any suitable manner such as by means of angle irons 13. The top of the structure is formed by the wall 14 which is alsoconstructed of fiber board and angle irons 15 are secured over the edges of the top and the adjacent side and end walls.

The bottom of the structure is formed in any suitable manner.

The front 16 is constructed of any suitable material such as wood and this front is provided with door openings closed by suitable doors 1?. l8. and each of the doors is preferably provided with a panel 19 constructed of fiber board and the doors are insulated bv means of suitable insulation 20. such as cork or the like andwhich insulation is arranged between the spaced walls 21. also constriicted of fiber board.

The doors engage or abut against the jambs :22, secured in position in any suitable manner. Arranged within the structure thus formed and preferably secured to the inner faces of the uprights 10. are walls which are also constructed of fiber board, and these walls are secured in position in anv suitable manner. Additional uprights 24 are arranged between the walls 12. preferably adjacent the uprights l0 and a similar wall 25. constructed of fiber board is secured to the outer faces of these uprights Ql so as to form dead air spaces 26 between the outer walls 11 and the adjacent walls 25 of the structure. Between the walls 23 and 25 is arranged suitable insulating material, such as cork insulation 27. whereby the interior of the structure will be insulated against heat.

The inner faces of the walls 23 are coated with any suitable material to prepare the faces for a coating 28 of enamel or finishing material.

lVith this improved structure it will be manifest that an extremely light. simple, durable and cheap construction will be produced. and a structure which will be thoroughly insulated against heat at a cost materially less than the cost of a similar structure made of wood or other material.

lVhat is claimed as new is:

1. A refrigerator having outer walls constructed of fiber board. corner uprights to which the fiber is secured. inner walls constructed of fiber board. said inner walls secured to the uprights and spaced from the outer walls. additional uprights within the spaces and adjacent the first said uprights. said additional uprights extending only partially across the respective spaces, partitions constructed of fiber board. arranged in the spaces and secured to the said additional uprights, said partitions cooperating with the inner walls of the refrigerator to form insulation spaces, and insulating material in said insulation spaces, the spaces between the partitions and the respective adjacent outer walls forming dead air spaces.

2. A refrigerator having outer walls constructed of fiber board, corner uprights to which the fiber is secured, inner walls constructed of fiber board, said inner walls se- -cured to the uprights and spaced from the outer .walls, additional uprights within the spaces and adjacent the first said uprights, said additional uprights extending only par tially across the respective spaces, partitions constructed of fiber board, arranged in the spaces and secured to the said additional uprights, said partitions cooperating with the inner walls of the refrigerator to form insulation spaces, insulating material in said insulation spaces, the spaces between the partitions and the respective adjacent outer walls forming dead air spaces, and a finish ing coating of enamel on the exposed faces of the said inner walls.

3. A refrigerator having outer walls conof two subscribm structed of fiber board, corner uprights to which the walls are secured, inner walls spaced from the outer walls, intermediate g engaging over the adjacent edges of the walls for securing said edges.

In testimony whereof we have signed our names to this specification, in the presence witnesses, on this 27th day of February, .D. 1915.
